Application filed September 13, 1928. Seria1-No."305 -,804.

This invention relates to grating apparatus, and more particularly to poWer-graters utilizing a conical grating element.

It is an object of the invention to provide an improved device of the character set forth, in which an improved removable conical grating element is provided.

A further object of the invention is to provide in a device of the character described,

1 1a removable grating chamber which is provided with a plurality of radially extending barriers adapted to retain the material to be grated against the grating surface.

A further object of the invention is to pro- "vide in a device of the character described, a

chamber adapted to receive the grated material, said chamber being at all times in munication with the grating surface, said chamber being provided with means whereby the grated material may be removed from the chamber.

Other objects of the invention include the combination and, interrelation of parts,

whereby the whole forms an improved, efii- Icient apparatus which Willbe economical to construct and easy to operate.

Numerous other objects and features of the present invention will be apparent from a consideration of the drawings, in which- Fig. 1 is a top plan view of one form of my present invention. 1

Fig. 2 is a side elevation partly 1n section of that form of the invention illustrated in Fig. 1.

Fig. 3 is a vertical sectional vlew of the grating chamber removed.

Fig. 4 is a view partly in section of the grating element.

Fig. 5 is a detail view showing the structural features and assembly of the apparatus.

Referring more particularly to the drawings, there is provided a base 10 through which extends a driving shaft 11, the outer endsof which may be provided with suitable driving pulleys 12, and intermediate the ends of which the bevelled driving gear 14 is provided; shaft 11 is preferably journalled in diametrically opposite sides of the casing 10 59; as at 15, and is also preferably centrally j our- COIII- nalled-at 16 in a vertically extending ournal member. 17 ,in thetopof'which a vertical driv-' I ing shaft 18 is journalled being provided'with suitablethrust bearings as at 19. Therver tical shaft 18 isqprovided?with a'cooperating bevel gear 20, and it may'readily-be seen that by cooperation of the: gears 14- and 20,. the

verticalshaft'18 is'caused torotate in-=re sponsetotheapplie'd forces-on the pulley wheels 12. I v

-A- suitable shaft and=gear'housing*is provided for the. gears 14,20, shaftv llandaE-portionof the vertical shaft 18. This housing ineludes an: under pan 21 which is'p'rovidedvat 1 its'center'with the member 17 and withfa cooperating cover'which includes-a frusto+conical centralmp'ortioni22 andaan inclined?floori23.

Within the housing, su iztable lubricants Y may be provided. If desired, the: entire...

housing may be packed with :rlubricating grease. 1

-It will be noted from further considera tion I of the .invention that the housing .pre-

vents the contact oft-he. grated material with the necessary lubrication for the. gearingan d i shafts. It will alsobe'inoted thatwthe .upper surface .ofthe floor 23==and conical member 22, together with the under panv 21-formfa tubularihous ing for the shafts11and'18 and the gears 14' and 20, but which provide space for the passage=ofgrated material between the'walls .10, wherebyit-may come torest and be received upon: the. top 2% of .a-isuitable supporting surface for the apparatus.

Mounted upon. the; casing 10 and .removably secured thereto by the provision of' bifurcated extending 'lugsr25 and acooperatingboltrand wing nut assemblys26 'secured to the housing 10, a-tgratingchamber is provided including vertically. extending: side walls '27,

which join at the toplto form a seat forrain" inserted-bearing 29 for theiupper end. ofcthe verticalshaft'18; *The baifles-QTt-aper down-.v

wardly to provideaarconicalffree-space within wherebywthere is provided an inclined surface tendingto urgethe materialztorbe grated .90 andminward extending Jbaflie omembers =28 downwardly and forcing it in contact with the grating surface.

Within the free space and slightly spaced from the inner edges of the baflles 28, there is provided a grating element 30 which comprises a central vertical bore 81 adapted to receive the shaft 18 from which extend radially supporting members 32 and a conical surface 33 which is supported at its lower.

end bythe members 32. Thelower end of the central portion isgrooved as at 34 to be received upon a pin 35 of the shaft 18, whereby rotation of the shaft 18 will effect rotation of the grating element 30. A removable grating surface 36 is provided over the sides 33 of the grating element, and may be crimped as at 37 about the lower edge thereof for securing it rigidly thereto.

By referring to Figs. 2 and 5 of the drawings, it will be noted that the grating element 30 is positioned in slightly spaced relation to the radial members 28 and the side walls 7 it may be removed, and is received upon the 27, the grating material being supplied through the open top of the grating chamber andbetween the radial members 28. Ro-

tation of the grating element 30 causes con tact of the material to be grated as indicated shaft, said baffle members being inclined in the direction of rotation of said grating surface for forcibly directing the material to be grated into contact with said conical grating surface.

at 38 with the grating surface 36, and the material after. grating. moves downwardly over the con cal surface, passing between the lower edge thereof and the walls 27, and into thechamber within the body 10 from which surface 24. Thus, it may readily be seen that we have provided an apparatus of simple and improved construction for readily carrying out the objects ofthe invention as herein recited.

It will be readily understood that numerous changes and'modifications of the invention may be resorted to without departing from the spirit or scope of the appended claim.

WVe claim:

In a device of the character'described, a,

receptacle for receiving grated material, a grating chamber detachably superposed thereon, driving mechanism within said receptacle, said driving mechanism including a horizontal drive shaft extending through said receptacle and journaled in diametrically opposite sides thereof, a bevelled driving gear intermediate the ends of said horizontal shaft, a verticaldrive shaft extending through said grating chamber, a bevel gear provided at the lower end of said ver-
